Kōsa

Kennyo , also known as Kōsa (光佐), was the 11th patriarch of the Hongan-ji lineage of Jodo Shinshu Buddhism, and Chief Abbot of Ishiyama Hongan-ji, cathedral fortress of the Ikkō-ikki, during its siege at the end of the Sengoku period. Similar to his father, Shōnyo, Kennyo engineered many alliances, and organized the defenses of the cathedral to the point that most at the time considered Ishiyama Hongan-ji to be unbreachable.
